Gigabyte H170N-WI-FI Motherboard
Intel Dual Core i3-6100T
Windows 10 x64
Other than the FLIRC I only have a 'Logitech Mini Receiver' for a Logitech LX710 keyboard and mouse. Yesterday I tried removing the Logitech Mini Receiver USB device and still had trouble waking the machine.
Happy to try any troubleshooting steps to help you.

Please keep us all updated - i have a new HTPC thats been sitting unused for 5 months waiting for this one last fix.
Bought the FLIRC for the advertised wake function and really don't want to look into returning it and using MCE receivers again.

Apologies for not updating the thread earlier - I have been away. I have updated to .15 and the PC will wake a few times, but after a while it stops. I can still wake up using my Logitech keyboard (the type with a RF USB dongle). PC runs Win 10 x64. Hibernate disabled. All drivers up to date, and I have checked BIOS to make sure theres nothing sleep related enabled.

I havent, as I assumed that after it worked a few times that I didnt need to re-register. Since my last post, its worked, still testing (i have the PC set to sleep every few minutes, and when it does I grab the remote and test)
